Important information 

  1. From 1 October 2022, 100% renewable electricity is only available to customers who currently have an electricity smart meter or who have a smart meter installed. You can book a smart meter installation or get more information online. Not all customers may be able to have a smart meter installed. Terms and eligibility criteria apply.  If you are on a fixed contract you will still receive 100% renewable energy until the end of your contract. The renewable electricity we sell is backed by renewable certificates (Renewable Energy Guarantee of Origin certificates, also known as REGOs). Get more details on REGOs and how these work. A proportion of the electricity we sell is also purchased directly from renewable power generators in the UK.

  2. 12 month contract applies. No claims can be made in the first 30 days. Terms, conditions, eligibility criteria, exclusions and cancellation charges apply. Offer available to new customers only, and not available for existing SSE Home Services, CORGI HomePlan, OVO HomePlan and OVO Energy boiler cover customers. Offer expires 30/03/23. Check out our full terms and conditions for more info.

  3. OVO Energy plants 1 million trees across the UK each year with its tree planting partners, The Conservation Volunteers and the Woodland Trust. Trees absorb carbon dioxide from the atmosphere, so planting trees helps to slow down climate change.

  4. OVO is made up of the energy suppliers SSE Energy Services, OVO Energy, and Boost. Together, we power over 4 million UK homes with energy. This figure is correct as of 22 January 2023.
